SPECIFICATION forming part of Letters Patent No. 740,030, dated September 29, 1903. Application filed February 9, 1903. Serial No. 142,480. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM MoCLosKEY, a citizen of Canada, residing at the town of Essex, in the county of Essex and Province of Ontario, Canada, have invented certain new and useful Improvements in'Oultivators, of which the following is a-specification.

This invention relates more specifically to that class of cultivators known as sulkycultivator-s provided with independentlypivoted and verticallyadjustable shovelframes.

The invention consists in the novel construction, arrangement, and operation of a device for raising and lowering the shovelframes, comprising two separate and independent devices, one for each shovel-frame, each actuated by a separate lever,in combination 'with an alinement-lever, with which said levers may be associated for operation as a single lever for the raising or lowering of both shovel-frames jointly together, all as more fully hereinafter described, and shown in the accompanying drawings, in which Figure 1 is a sectional side elevation of a cultivator embodying my invention. Fig. 2 is a rear elevation. Fig. 3 is a plan view; and Fig. 4is a horizontal section on line 4 4, Fig. 1.

In the drawings I show my invention as applied to a cultivator of otherwise known construction.

A represents the wheels; B, the arched axle; D, the draft-pole secured between the forward ends of the side bars; E, the steel carrying-frames; F, the draft-yoke, to which the forward ends of the-shovel-frame are pivotally secured; G, the draft-rods; H, the seatframe, and H the seat.

I I are levers for raising and lowering the shovel-frames independently of each other. Each lever is divided at its lower end into two branches at b, the former pivotally con- .necting the lever to a hanger J, depending that if they are inalinement with each other they may be grasped together by one hand and singly moved together forward and backward as one single lever, and in so moving them together both shovel-frames will be simultaneously raised and'lowered. The levers are adapted to be locked in any position into which they may be turned by means of two parallel bars L, secured longitudinally upon the frame and provided with a series of adjusting-holes. Each of the bars L carries a running-sleeve M, pivotally connected to one end of the connecting-bar N, the other end of which is pivotally connected to one of thelevers, respectively' Each connecting-bar carries a locking-latch composed'of two lever members 0 O, the former adjacent to the handle-grip of the lever and provided with a similar handle-grip 0 and the latter provided with a locking-pin o, entering an aperture in the runningsleeve and adapted to register with any of the adjusting-holes in the bar L upon which it travels. The latch members are pivotally secured upon opposite sides of the connecting-bar which carries them, and their inner ends are transversely connected by a bolt 19, upon which a coil-spring q is sleeved, all so arranged that the operator by grasping the handle-grip of either lever may readily grip the latch, and at the same time if the operator takes hold of the handle-grips of both levers in'case he 'wants to'operate them jointly he can grasp and operate both locking -latches with the same hand.

To facilitate the act of alining the two levers I I when desired and moving them together in alinement with each other, I have devised what I call the alinement-lever P, which in form duplicates those portions of the two levers I I on which the handle-grips are formed and which represent the halves of a yoke. This-lever is pivotally secured to the hangers J, so as to turn upon the same axis as' the levers I I, and by means of a spring Q itis firmly drawn forward against the levers I I. If these levers are not in alinement with each other, the alinement-lever will be drawn up tightly against the rearmost one, and it both levers are in alinement the alinementlever will be drawn up tightly against both ward lever can be drawn into alinement with the other, and thus in either case the alinement-lever practically serves as a stop in bringing the levers into alinement and thus greatly facilitates the operation of the levers, while at the same time each lever can be operated absolutely independently of the other.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a raising and lowering device for the shovel-frames of a sulky-cultivator, a pair of levers pivotallysecured upon a common axis in front of the drivers seat on opposite sides of the longitudinal center and to which levers the shovel-frames are connected respectively for raising and lowering them independently of each other, said levers being provided at their free ends with handle-grips projecting laterally inward and adapted to be moved in contiguous alinement with each other and constitute a single grip when joined by the hand of the operator for the joint operation of both levers.

2. In a raising and lowering device for the shovel-frames of sulky-cnltivators, a pair of levers pivotally secured upon a common axis in front of the drivers seat on opposite sides of the longitudinal center respectively and carrying the shovel-frames independently adjustable by the movement of each lever from and toward the driver, said levers formed with handle-grips projecting laterally inward and adapted to move in contiguous alinement with each other and carrying independently-operating latches provided with handle grips adapted to move in contiguous alinement with each otherand carrying independently-operating latches provided with handle grips adapted to move in contiguous alinement whereby the hand of the operator may operate both levers in conjunction.

3. In a raising and lowering device for the shovel-frames of sulky-cultivators, a pair of actuating-levers, one for each shovel-frame, pivotally secured upon a common axis on opposite sides of the longitudinal center and having their free ends bent inwardly and adapted to form complementary parts of a yoke-grip in joining them together in alinement with each other by the hand of the operator in grasping contiguous portions.

4. In a raising and lowering device for the shovel-frames of sulky-cultivators, a pair of actuating-levers, one for each shovel-frame, pivotally secured upon a common axis on opposite sides of the longitudinal center in reach I from the drivers seat and having their free ends bent inwardly and adapted to form complementary parts of ayoke-grip in joining them together in alinement with each other by the hand of the operator, in combination with independent locking-latches, one for each lever, provided with handle-grips adja cent to the inwardly-bent portions of the levers and adapted for joint operation by one hand in the joint operation of both levers.

5. In a raising andlowering device for the shovel-frames of sulky-cultivators, a pair of actuating-levers, one for each shovel-frame, pivotally secured upon a common axis on opposite sides of the longitudinal center and having their free ends bent inwardly and adapted to form complementary parts of a yoke-grip in joining them together in alinement with each other by the hand of the operator, in combination with an alinement-lever pivotally secured upon a common axis with the levers and forming a yoke corresponding with and adapted to cooperate with that of the levers, substantially as described.

6. In a raising and lowering device for the shovel-frames of sulky-cultivators, a pair of actuating-levers, one for each shovel-frame, pivotally secured upon a common axis on opposite sides of the longitudinal center and having their free ends bent inwardly and adapted to form complementary halves of a yoke-grip for joint operation of the levers with one hand, in combination with an alinement-lever pivotally secured between the aforesaid levers upon a common axis therewith and forming a yoke-grip adapted to cooperate with the halves of the yoke grip formed by the levers, and a spring adapted to hold said alinement-lever in engagement with the other levers.

7. The combination,with the carrying-frame and the shovel-frames, of the raising and lowering levers pivotally secured to the carrying-frame in line with each other and each provided with alateral offset carrying one of the shovel-frames respectively, the inwardlyturned grip portions formed on the free ends of the levers and forming complementary halves of a yoke-grip between the lovers, the parallel locking-bars secured upon the carrying-frame, the latch-carrying bars pivotally secured at one end to the levers and at the other end to the travelingslides upon the locking-bars, the locking-latches carried by said bars, the alinement-lever pivotally secured between the raising and lowering levers and the spring adapted to hold said lever in engagement with the raising and lowering levers.

In testimony whereof I aflix my signature in presence of two witnesses WVILLIAM MCOLOSKEY.
